2025-02-05 CH spectra from the paper "First Search for Pulsed CH Maser Emission Stimulated by a Pulsar" doi:10.57760/sciencedb.fastro.00022 en This data collection contains CH spectra observed toward PSR J1644-4559 during pulsar ON and OFF phases, as well as CH opacity spectra. Observations were carried out using the Parkes ultra-wide-bandwidth low-frequency (UWL) receiver, targeting three CH Λ-doublet transitions at 3264, 3335, and 3349 MHz, each with a total integration time of approximately 71 hours. All spectra were computed after applying Local Standard of Rest (LSR) velocity corrections, which were implemented for each 10-minute observation. pulsars; spectral lines; masers Mengting Liu Di Li J.
